CITOSTEPCITOSTEP machines are intelligent MIG/MAG welding installations with voltage switchingtechnology and numerical control of the parameters. Robust and reliable, they contain aninnovative Easy Synergic Program (ESP) for an easy set up of the equipments.Particularly suitable for shipyards, boiler factories, railway equipment and road transportsectors, these machines are able to weld low thickness metal sheets with reduceddistortion and low emission of spatters.Criteria choice for CITOSTEP RANGENameCITOSTEP 250CCITOSTEP 300CCITOSTEP 350C/SCITOSTEP 450S/SW2Main powersupplyThree-phase230 V / 400 V /-10%(50-60Hz)TechnologyESP StepcontrolWeldingcurrent rangeDuty cycle@ 40 CWire feederWirediameterEnclosedSeparate4 rollers35 - 250 A250 A - 35%0.6 - 1.2 mm - 35 - 300 A300 A - 35%0.6 - 1.2 mm 35 - 350 A350 A - 35%0.6 - 1.2 mm 50 - 450 A450 A - 35%0.6 - 1.6 mm-

Advanced functionalities: ESP & EFQIn ESP mode, welding becomes easyand intuitive. The purpose of the ESP(EASY SYNERGIC PROGRAM) is to helpthe operator through adjustment of thewelding generator to achieve an optimizedwelding condition for any given application.ESP Front panel➋ Select gas of protection and metal sheet type.➌ Select thickness.➍ S et up the power switchesand inductance followingthe indications of leds.➊ S elect wirediameter.And just weld !When ESP is deactivated (manual mode):the power source is adjusted like any standardsource (select voltage, wire speed and choke).EFQ (Easy FreQuencer)This welding process can be used to weld low thickness metal sheets ( 4 mm)for edge-to-edge welding. Thanks to this functionality, the heating is reduced andthe impacted area is decreased, avoiding the metal sheet’s distortion and collapse.To weld with EFQ, switch the equipment in Intermittent mode.Intermittent modeIt is a 2T mode with two phases controlled by the timing adjusted in the “cycle” menu:a welding phase and a waiting phase (no weld) up to the release of the trigger.Head to headVertical ascendant10 good reasons to choose CITOSTEP for industrial installations:➊ Robustness guaranteed by qualified crash test.➋ E SP settings assistance to obtain the right welding➌➍➎parameters instantly.Q uality of transformer and choke that guaranteeexceptional welding of steel, stainless steel or aluminum.C ontrol of choke for instant arc strike with minimalspatter.D uty cycle at 40 C meeting industrial productivityrequirements due to an optimized cooling.➏ C omplete welding cycle controlled by microprocessorcard for high flexibility.➐ A ccurate and constant numerically controlled wire feed.➑ D isplay of parameters (voltage, current, speed)essential for the conformity of operating modes.➒ E nhanced reliability and life expectancy due to protection➓of switching equipment in a dust-proof compartment.F ully compliant, tested for EMC immunity and enduranceto enable operations in harsh industrial environments.3

The MIG/MAG expertThe MIG/MAG processPrincipleThe MIG/MAG weldingprocess uses an arcunder gaseous protection. The electrode is ametallic wire. The electrode, the metal transferred in the arc andthe weld bead are protected from the atmosphere by an inert gasfor MIG welding andan active gas for MAGwelding. In manualwelding this processis called semi-automatic because the wire isfed automatically assoon as the arc starts.WeldingwireNozzleContacttubeGas flowElectricarcGasshieldingWelding wireGasshieldingElectricarcWorkpieceTorchContact tubeNozzleBeadArc transfer modesShort-Arc transferThe Short Arc has a low spatter rate with good wetting and issuited to welding thin steel plate, working in position and penetration passes This mode is characterized by alternating shortcircuits and light arc.Speed Short-Arc transferThe Speed Short Arc allows a high travel speed due to a rigidarc and a cold regime. It is very efficient for welding thin steelplates, working in position and in closed angle and filling bevels.The SSA is used for short circuit welding though the normalglobular regime travel speed domain.Globular transferMetal is transferred in the arc as large drops with hardly masterred trajectories. It’s a transfer mode giving low quality results.Spray-Arc transferWork pieceApplicationsShipyardsShipbuilding applications, bothrepair and construction, are aparticular focus for this equipment,that combines ergonomics androbustness with very high weldingquality. A small, lightweight wire feed unit facilitates access to allthe compartments in a ship’s hull. The addition of a water coolingunit in the power source makes it possible to use a smaller, liquidcooled torch, facilitating these welding operations.Railway equipmentQuality and productivity requirements are important in the railwayconstruction sector. This is whyweimprovetheweldqualitybyadaptingour power sources and procedures in response tothe developments in materials used within this marketMetal is transferred in the arc as small droplets. The mode isvery regular but requires high welding parameters and thereforeis usable only for thickness above 5 mm.Boiler factoriesThe great diversity of welding applications in this sectormeans that MIG/MAG weldinginstallations have to be versatile. Used for spot weldingsheet, but also for penetration pass and joint filling,CITOSTEP units are specially adapted to these operations. Numerical control of wire speed helps to keep the welding parametersconstant, ensuring excellent reproduction of the welded joints.Road transportMade from a wide rangeofmaterials,companies have to adapt to therapid changes in manufacturing practices whilst remaining in control of quality. The CITOSTEP settings assistance system (ESP) facilitates this adaptation while7
